RIM-REMOVEB FOR WHEELS.

I Specification of Letters Patent.

Patented Aug. e, 1918.

Application filed November 30, 1917. Serial No. 204,768.

and useful Improvements in Rim-Removersfor Wheels, of which thefollowing is a specification. I

This invention relates to tire rim removing and replacing tools, havingfor lts object to provide a tool which will greatly facilitate removalof the rim from the wheel and will likewise facilitateengagement of therim with the wheel.

Another object is to provide a very simle tool which may be convenientlycarried in the tool box of the automobile, which may be successivelyused by a novice, both for removing and replacin the mm, and which maybe manufacture at a very low cost.

The above and other objects and advantages of this inventionwill be inpart described and in part understood from the following, description ofthe present preferred embodiment, the samebeing illnstrated in theaccompanying drawings, in which Figure 1 is a perspective view of a rimremover and replacer constructed in accordance with my invention andillustrating the application of the same on a portlon of a wheel, aninside view of the latter being shown.

Fig. 2 is a side elevational view of the tool, and

Fig. 3 is a top plan view of the same.

In the drawings in order to illustrate the application of my invention aportion of a wheel 1 is shown upon which the usual tire and rim ismounted.

The .tool constructed in accordance with my invention consists of a bodyor' shank 2 which in this instance comprises an elongated barpreferably. flat in cross section and equipped on one end with a handle3. The opposite end is bent at an an le so as to provide a bell cranklever 4 whic is integrally formed on the shank 2 thereby providing astructure substantiall U-shaped in elevation. The free terminal of the'bell crank lever is recessed as indicated at 5 to provide, a seat forthe inner margin of the wheel rim. A recess 6. is formed in the outermargin of the bell crank lever 4 at the angle of the latter'and providesa seat for the reception of the outer margin of the rlm when the tool isused as a rim replacer. It will also be noted that the outer margin ofthe bell crank lever, adjacent its 'ointure with the shank 2 is a'rcuateas at so that in an emergency the tool could be used as the jack inwhich case the part 7 may be placed in contact with the support uponwhich the vehicle is located, and the free terminal of the bell cranklever engaged with the tire or some art of the wheel adjacent thesupport. he part 7 will act as a fulcrum to facilitate operation of thehandle 3.

A metal strap 8 is provided one end of which has a plurality ofapertures formed therein any one of which is registerable with anopening formed in the shank 2 adjacent the jointure of the latter withthe'bell crank lever 4. Said openings are adapted to receive the shankof a bolt 9 which serves as an axis about which the shank moves whenpressure is exerted on the handle 3. The inner end of the strap 8 isbent to form a hook'10 which embraces a spoke of the wheel 1 as shown toadvantage in Fig. 1.

In use of this device as a rim removing tool the tool is associated withthe wheel in the manner illustrated to advantage in' Fig. 1. In thisposition it will. be seen that the recess terminal 5 of the bell cranklever is engaged with the inner margin of the rim of the wheel, and thehook 10 engaged with a spoke of the wheel. When in this position upwardpressure on the handle 3 will cause the rim to be forced outwardly fromthe wheel. When the tool is used as a rim replacer, the recess 6 isengaged with the inner margin of the rim and the strap 8 turned asemi-revolution on its axis, in which position the hook 10 will be on aline substantially coincident with the longitudinal axis of the shank 2.The hook when in this position is of course engaged with one of thespokes, and a downward pressure on the handle 3 will cause the rim to beforced inwardly on the wheel. It is of course understood that byproviding a plurality of a ertures in the strap 8, an adjustment o thelatter may be had so as to conform to wheels of various sizes.

It will be understood that the above description and accompanyingdrawings comprehend only the general and referred embodiment of myinvention an; that various minor changes in details of construction,

proportion and arrangement of parts may be made within the scope of theap ended claims without sacrificing any of 't e ad. vantages. of myinvention. a

1. A wheel rim remover including a shank equipped with a handle on oneend and having a' U-shaped extension on its opposite end, the terminalof which is recessed to receive the rim when the latter is to beremoved, said extension having a recess at one of its angles to engagethe rim when the latter is to be replaced on the wheel, and a spokeengaging means adapted to lie in alk horizontal position in relation tothe sha 2. A Wheel rim remover and replacer including a shank providedwith a U-shaped extenslon, said extension having a plurality of recessesfor engaging with the rim, an adjustable metal strap having a hook onone end and said strap bein pivotallyconnected to-one side of said s ankadapted to lie in a longitudinal position in tion to the shank.

In testimon whereof I afiix my signature in presence 0 two witnesses. j
